Electromobility with INSYS icom

Communication technology for the E-mobility charging infrastructure

Charging solutions for the mobility turnaround

The energy transition is playing an important role on the way to climate neutrality. Road traffic will contribute its share by replacing combustion engines with electric drive systems based on green electricity. In addition to drive and battery technology, charging options are the key success factor here. Numerous, reliable and flexible charging points are therefore essential to make e-mobility viable and to provide the future infrastructure for road traffic.

This is by no means relevant only to energy suppliers, grid providers and automobile companies. Every company with interfaces to E-mobility needs to expect changes and opportunities, and to actively shape them: it is entirely possible that in your environment, too, there will be a need for action in the areas of charging station solutions, charging network operation or fleet management.

Charging infrastructure in practice

The following interactive illustration shows the individual processes of a charging operation:

According to ISO15118-3, routers such as the Powerline Green PHY™ from INSYS icom can securely guarantee the data communication between charging point and vehicle, thus ensuring the optimal charging process.

The basics of charging solutions

The highest availability of charging points is essential for the mobility transition. The required data communication between the charging stations is implemented with Powerline Green PHY™ from INSYS icom.

High availability

If you have to charge, you have to charge. Just as petrol pumps at a filling station very rarely fail to work, the availability of charging stations should always be high.

IT security plays an immense role in data communication at charging points. Routers & gateways are certified by TeleTrust and therefore have a high level of IT security.

Secure communication

Whether it’s reservation, release, charging or billing: the entire process must be consistently protected against manipulation or errors. This is essential for providers and users.

Intelligent data communication with the Powerline Green PHY™ from INSYS icom ensures trouble-free operation between charging point and electric vehicle.

Trouble-free operation

The individual process steps between reservation, charging and billing must be transparent and trouble-free.

Typical requirements and approaches for charging solutions

With INSYS icom products, manufacturers of charging columns of AC and DC charging points benefit from reliable data communication with IT security, remote access options and Powerline according to ISO15118-3.

You provide charging stations as a complete technical solution that can be used in private or public spaces. AC-based solutions deliver charging capacities of up to 22 kW, while DC solutions with direct current enable so-called “fast charging stations”. Unlike the wallbox for the home, public charging stations are subject to strict requirements for functional safety and IT security in order to comply with applicable standards and robustness requirements.

We support charging station manufacturers with reliable internet communication for the charging station (versatile router technology and mobile radio), remote access options and IT security, especially for operation and billing. In addition, we provide know-how, advice and solutions in data communication between the vehicle and the charging station (powerline as per ISO15118-3).

INSYS icom convinces in electromobility with expert knowledge around the terms Powerline Green PHY™, AC and DC charging columns, ISO15118-3, IEC 61851, load management, type 1 and type 2 plugs, as well as combo plugs, wallboxes and superchargers.

Basic technology

Powerline Green PHY™

A hardware communication solution, often in the form of a specialised chip, that enables data communication within power grids. This uses a form of the powerline protocol, which is also known for the extension of IP networks via sockets, accordingly allowing charging points and vehicle systems to communicate for the switching, start and end of the charging process.

AC/DC

AC stands for alternating current. Charging capacity of up to 22 kW is typical. DC means direct current. Much higher charging capacity of 200 kW and more is possible here, but direct current is predominantly found in industrial environments and along motorways. DC charging still dominates in the commercial sector and along motorways.

ISO15118-3

Protocol for data communication between an electric vehicle and a charging station, which supports the Combined Charging System (CCS). Smart charging and plug & charge are envisaged in terms of energy storage, load/charge management in the smart grid and for flexible charging rates.

IEC 61851

This basic standard, which is intended for electrified vehicles, regulates different charging modes on the “physical layer” in order to keep the charging start and the charging session compatible via different high-level protocols (e.g. ISO15118).

Load management

In most cases there isn’t an unlimited amount of charging current available for multiple charging stations. Overall power therefore has to be intelligently managed and distributed, taking into account the number of vehicles to be charged. This is one of the important functions in the field of fleet management or at locations with many charging points.

Type 1 and type 2 plugs and combo plugs

This is the term used for the five-pin (Type 1) and seven-pin (Type 2) physical charging plugs for various electric vehicles. Charging stations and vehicles in Europe mostly use the Type 2 plug. For charging, IEC 61851 is used to manage the charging process. The combo plug supplements Type 2 with additional power contacts and a fast-charging function up to 170 kW.

Wallbox

This refers to a charging station that can be conveniently mounted on a wall. These are often solutions for end users.

Supercharger

The brand name and technology used by the vehicle manufacturer Tesla. These charging stations offer a lot of charging power (> 100 kW), but are based on proprietary technology and are usually not available for use by others.
